In-depth discussion of energy storage battery technology, battery energy storage value evaluation research and battery energy storage device applications, etc.
In urban power grids, the daily maximum load of the summer peak power consumption generally occurs around noon, but the curve between the noon peak and the light peak is flattening day by day, and the daily maximum load in some residential areas has appeared during the night light peak period. The continuous increase of […]
①Reduce the operating costs of power generation companies and power grid companies, and reduce users’ electricity costsThe operation and maintenance of the energy storage system is relatively simple, while the operation and maintenance of the power plant or the power grid are relatively complicated. After the energy storage system is put into operation, the operation […]
①Improve the safety and reliability of power supply of the power gridAccording to the summary of the current research results of battery energy storage system, the electric energy storage system can be applied to the following fields in the power grid:1) Voltage control: Support heavy-load feeders, provide power factor correction, reduce the restriction requirements of […]
①Change the energy structure, reduce system fuel consumption and save energyThe power industry is currently developing rapidly. The main problem in the operation of the power system is the power supply contradiction caused by the unreasonable power supply structure, especially in some power grids dominated by thermal power, due to the lack of peaking balance […]
①. Peak shaving and valley filling, provide reserve capacity, and ensure the safe and stable operation of the power gridOne of the characteristics of grid operation is that power generation, power supply and electricity consumption are completed at the same time, and cannot be stored on a large scale and for a long time. The […]
Battery energy storage is mainly through the oxidation-reduction reaction of the positive and negative electrodes of the battery for charging and discharging. The battery energy storage system (BESS) is composed of batteries, DC-AC inverters, control devices and auxiliary equipment (safety and environmental protection equipment), and is currently the most widely used in small distributed power […]
Electric energy can be converted into chemical energy, potential energy, kinetic energy, electromagnetic energy and other forms for storage. So far, people have developed various forms of energy storage systems, which can be divided into physical, electromagnetic, electrochemical, and phase-change storage systems according to their specific methods. There are four types of ability. Among them, […]

Safety, high quality, and economy are the basic requirements for the power system. In recent years, with the growth of global economic development and the implementation of market-oriented reforms of power companies, the operation and demand of the power system are undergoing tremendous changes. Some new contradictions have become increasingly prominent. The main problems are:①The […]
